The 32-year-old confessed killer wants to explain why he plans to keep fighting against the multiculturalism he despises, lawyer Vibeke Hein Bæra told radio news show P4 Nyhetene.

“He’s writing about why he wants to continue his battle,” she said.

“It’s not yet known if he wants to call it a continuation of his manifesto or a book.”

This week saw the lifting of restrictions on Breivik, giving him access to the news media for the first time since his arrest.

“He has looked forward to orienting himself in what’s happeing in society. At the same time, his main focus for now is the text he’s writing,” said Hein Bæra.

Norwegian publishers told newspaper Aftenposten that Breivik would likely be able to find a company willing to put out his work.

“A publishing company is not meant to function as a censorship authority and none of the author’s opinions have anything to do with the publisher,” said Anders Heger from publisher Cappelen Damm.

“At the same time, Norwegian publishers don’t have a duty to publish. Personally, I’d have no hesitation in rejecting this, since I don’t see any reason to give him the opportunity of earning money from those awful events.”

A psychiatric report submitted to prosecutors concluded that Breivik suffers from paranoid schizophrenia. He is expected to be sentenced to closed psychiatric care after his trial, which begins in April 2012.
